YINGHUA ADUM1301BRWZ Digital Isolator SOIC-16 semiconductor

Component identity

The ADUM1301BRWZ is a 16-pin digital isolator supplied in an SOIC-16 package. It provides galvanic isolation for signal paths in industrial, automotive and instrumentation designs. Engineers specifying board-level isolation for SPI, I²C or generic logic interfaces will use this part. It is not suited for designs that require integrated power isolation or higher channel counts than the device provides.

Thermals and power

The supplier data does not quote thermal resistance, operating current or supply-voltage range for this isolator. Power dissipation and noise performance will therefore depend on the chosen supply rails, data rate and PCB layout. Designers should consult the manufacturer datasheet for absolute maximum ratings and recommended operating conditions before committing to a layout.

Upgrade context

This part replaces earlier-generation digital isolators in a 16-pin SOIC footprint when a pin-compatible drop-in is required. The jump is worthwhile when a bill-of-materials consolidation demands a single-source 1301-series device listed by the manufacturer in February 2025. It does not address designs that need wider creepage, reinforced insulation ratings or a different package style.
